Abstract

L'invention se rapporte au domaine de l'immunothérapie. La présente invention concerne des anticorps utiles dans des applications thérapeutiques et diagnostiques ciblant SIRPa humain, lesdits anticorps améliorant la présentation croisée d'antigènes à des lymphocytes T. L'invention concerne également des anticorps dirigés contre des isoformes spécifiques de SIRPa et sont capables de perturber l'interaction entre ces isoformes de SIRPa et CD47 humain pour une utilisation dans le traitement ou la prévention d'une maladie, ou dans des applications diagnostiques, et des procédés de production et/ou de sélection d'anticorps anti-SIRPa humains qui se lient avec des affinités différentes à plusieurs isoformes d'éléments SIRP humains.
